Lubricants that can deal with car noise and vibration issues
Compared to the past, today's cars focus on providing a smoother driving experience and a quieter interior environment in terms of design. Because of this, people are now paying more attention to the previously unnoticed issues of weak noise and slight noise.
Noise, Vibration, and Acoustic Vibration Roughness (NVH), as well as Buzz, Squeak, and Rattle (BSR), may be emitted by many internal and external components. These sources may include rubber in coatings, metal in plastics, and friction between leather and leather, or from engines.
Hank high-performance lubricants are the ideal choice for solving NVH and BSR, as they can:
- Easy application through spraying or brushing
- Not affected by harsh conditions such as rain, snow, ice, salt, dust, and dirt
- Resistant to fuel, coolant, brake fluid, and washing fluid
- Low evaporation or no characteristic changes throughout the entire lifespan of the car
- Compatible with all other substances and surfaces that may come into contact with
Meeting the expectations of drivers and passengers
Driven by customer demand, automakers have been attempting to reduce NVH and BSR through various passive design techniques and active technical features for many years.
Noise reduction and shock absorption performance are the main considerations for new car buyers - especially with the emergence of electric vehicles (EVs) - and often affect buyers' views on the quality and value of the car. In addition to the obvious annoyance, there are many important reasons why car buyers want to buy a quiet and smooth driving car.
This includes:
- Low and medium frequency noise can greatly cause driving fatigue
- High frequency noise can limit people's ability to hear conversations in cars
- Noise can cause headaches, stress, and irritability
- Vibration can cause irritability and discomfort
- For more information, please refer to the NVH white paper.
What occasions is Hank Automotive Lubricant suitable for?
The application of Hank PFPE lubricants in automobiles is generally divided into two categories:
Under the hood
In view of the aerodynamic requirements for more tight packaging, and the larger engine is replaced by the smaller turbocharged engine and supercharged engine to improve fuel efficiency, the temperature under the hood is gradually rising. Due to the ambient temperature under the hood exceeding 120 ° C (248 ° F), the number of automotive applications requiring PFPE lubricants is also increasing, including:
- Overspeed Decoupler for Alternator Drive Wheel
- Front End Accessory Drive (FEAD) Tensioner and Idler
- Throttle body bearing
- Exhaust Gas Recirculation (EGR) valve
- Intake manifold seal and actuator
- Fan clutch bearing
- Fuel system emission control valve
- Electric cooling system pumps and valves
- Ignition system plug cap
Internal and external noise, vibration, and acoustic vibration roughness (NVH) of automobiles
Hank Lubricant is a long-term and efficient solution to eliminate buzzing, creaking, and creaking sounds (BSR) inside and outside the car compartment. These PFPE lubricants and greases can effectively reduce the noise generated by friction between surfaces and mechanical vibration, without causing any material compatibility issues or the generation of harmful volatile organic compounds (VOCs). Some applications include:
- Weatherstrip and Elastomer Seals
- Internal plastic, metal, and leather surfaces
- Center console hinge and latch
- Door and trunk latch system
- Brake pedal assembly
- Seat devices (slide rails, headrest iron bars, and locks)
- Electric switch
- Airbag spring
- Exterior rearview mirror
- suspension bushing
